This option happens in multiple places (e.g., create a survey , start the qcode with a number, click save -> same error)

I confirm issue for 4.0.0 : same action .

I don't understand why this happen : this javascript is too complex for me…

start the qcode with a number

I think i already reported this one … less important : we have Save and add new ;)

Yea, will have to talk to @markusfluer about that.

An issue is here : https://github.com/LimeSurvey/LimeSurvey/blob/4f18b7a1cd3a14347693968129ceea9ef4d71ec0/assets/packages/adminbasics/src/parts/save.js#L97

(maybe) : this check only required value.

Most complete : $form[0].checkValidity(); or $form.checkValidity();
